Type material.
Holotype ♂ - CHINA: Sichuan Province, Yajiang County, Yajiang [27°50.119'N, 99°42.426'E, elevation 3285 m], 7 June 2001, X. Yu & H. Zhang (IZCAS). Paratypes: same area but Longjiangbian [27°49.119'N, 99°41.426'E, elevation 3265 m], 27 May 2009, X. Yu & H. Zhang - 1♀ (IZCAS).
Etymology.
The specific epithet, a Latinised adjective, refers to the type locality.
Diagnosis.
Judging from the shape of the bulb and the distal portion of the embolus, this new species is similar to Raveniola shangrila ( Zonstein and Marusik 2012, figs 33, 41) but can be distinguished by the slightly curved distal portion of the embolus (Figs 17 A–C, 19 A–C); conspecific females possess uniquely shaped receptacles, with the inner branches curved inward (Figs 18, 19D).
Description.
Male (holotype): TL 14.10, CL 5.60, CW 5.45, AL 6.20, AW 3.55. Eye diameters and interdistances: AME 0.19, ALE 0.25, PME 0.16, PLE 0.14, AME–AME 0.15, AME–ALE 0.07, PME–PME 0.45, PME–PLE 0.07. Leg lengths: I: 20.96 (6.09+2.24+5.45+4.49+2.69), II: 24.23 (6.47+3.27+5.83+5.45+3.21), III: 17.76 (4.49+2.18+4.10+4.55+2.44), IV: 22.56 (5.83+2.56+4.81+6.67+2.69). Venter as shown in Fig. 17G. Prosoma, palps and legs brown. Abdomen, including spinnerets, deep grey (Fig. 17D, G). Palpal tibia long, subcylindrical; cymbium apically with five short, stout spines; bulb long and pyriform; embolus gradually tapering to a slender bent tip (Figs 17 A–C, 19 A–C). Small PMS present, apical segment of PLS digitiform (Fig. 17D, G).
Female (paratype): TL 16.50, CL 6.75, CW 5.80, AL 7.25, AW 5.90. Colouration and most somatic characters as in the male. Eye diameters and interdistances: AME 0.21, ALE 0.35, PME 0.17, PLE 0.23, AME–AME 0.18, AME–ALE 0.12, PME–PME 0.53, PME–PLE 0.07. Leg lengths: I: 16.05 (5.05+2.30+3.90+3.05+1.75), II: 15.15 (4.25+2.75+3.30+2.80+2.05), III: 14.45 (4.30+1.95+2.85+3.25+2.10), IV: 19.90 (5.25+2.25+4.40+5.25+2.75). Receptacles divided into a long digitiform inner branch that is bent inward and a short club-shaped outer lobe that is bent anteriad (Figs 18, 19D).
